Implement automated branch protection rules for repository security and code quality

[Copilot]

This PR implements a comprehensive branch protection system for the Helixque repository to ensure code quality, security, and proper review processes across different types of branches.

What's Changed

Branch Protection Rules

Automated protection rules have been configured for all branch patterns with appropriate review requirements:

• main: 2 required reviews + code owner approval (most restrictive)
• develop: 2 required reviews (collaborative development)
• release/*: 2 required reviews + code owner approval (release safety)
• hotfix/*: 1 required review (emergency fixes)
• feature/*: 1 required review (feature development)
• bugfix/*: 1 required review (bug fixes)

All protected branches have strict status checks enabled and prohibit force pushes and deletions.

Implementation Components

1. Configuration Management (.github/branch-protection-config.yml)

   • Centralized YAML configuration for all branch protection rules
   • Easy to modify and maintain
   • Supports all GitHub branch protection features

2. Automated Application (.github/workflows/branch-protection.yml)

   • GitHub Actions workflow that automatically applies protection rules
   • Triggers on configuration changes or manual dispatch
   • Includes dry-run mode for testing changes safely
   • Comprehensive error handling and logging

3. Code Ownership (.github/CODEOWNERS)

   • Defines required reviewers for different parts of the codebase
   • Frontend team for /my-app/ changes
   • Backend team for /backend/ changes
   • Documentation team for *.md files
   • DevOps team for CI/CD configurations

4. Manual Management (.github/manage-branch-protection.sh)

   • Command-line script for local testing and administration
   • Validation, dry-run, and application capabilities
   • Useful for testing configuration changes before deployment

5. Documentation (.github/BRANCH_PROTECTION.md)

   • Comprehensive guide covering all aspects of branch protection
   • Troubleshooting information
   • Instructions for modifying rules

Benefits

• Security: Prevents accidental or malicious changes to critical branches
• Code Quality: Ensures proper review processes for all code changes
• Compliance: Enforces consistent review standards across the team
• Automation: Reduces manual administrative overhead
• Flexibility: Easy to adjust rules as the project evolves
• Documentation: Clear guidelines for contributors

Usage

The system works automatically once deployed. To modify branch protection rules:

1. Edit .github/branch-protection-config.yml
2. Test with ./github/manage-branch-protection.sh validate
3. Commit changes to main branch
4. Rules are automatically applied via GitHub Actions

For manual management or testing:

# Validate configuration
.github/manage-branch-protection.sh validate

# Preview changes
export GITHUB_TOKEN=your_token
.github/manage-branch-protection.sh dry-run

# Apply manually
.github/manage-branch-protection.sh apply

This implementation follows GitHub best practices and provides a robust foundation for maintaining code quality and security standards as the Helixque project grows.
